McLaren 720S GT3 Evo

TYRES

• Slicks (Dry), Front 27.3 PSI cold, Rear 26.8 PSI cold — targeting hot operating window 85–95°C (peak grip ~88°C) across the stint; for a single hot lap, blankets (if permitted) set to 80°C front/rear to reach window within 1–2 laps, otherwise push hard on out-lap to load tyres quickly.

ELECTRONICS

• TC1: 3 (minimal, max attack, high driver confidence required)
• TC2: 2
• ABS: 4
• Engine Braking: Medium-High (setting 4/6)
• Brake Bias: 54.5% front

DAMPERS

AERO

• Front Wing: 3rd slot (fixed splitter, no adjustment — run minimum front ride height legal for rake)
• Rear Wing: 8 (of 10) — high downforce bias for Maggotts/Becketts stability
• Downforce Level: High (Silverstone demands commitment through S-complex, straight-line loss accepted)
• Brake Ducts: Front 4 / Rear 3

KEY SETUP NOTE

• The 720S's mechanical platform is forgiving on traction but nervous at high speed with low wing — run the rear wing high (8) and stiffen the rear ARB only moderately; too much rear ARB combined with high coast diff lock will snap rotation entering Stowe. Prioritise a planted, high-wing setup through Maggotts-Becketts over straight-line speed on Hangar — the S-complex is where the lap is made or lost in this car.

TRACK GUIDE

• Maggotts-Becketts-Chapel: commit flat or near-flat; trust the high downforce setup, smooth minimal steering inputs — any lift unsettles the long wheelbase mid-engine platform through direction changes.
• Copse: full attack flat-out entry; the stiffer rear spring and high rear wing keep it planted — do not lift, trust the aero platform.
• Stowe: late, aggressive trail-brake entry; front stability from 54.5% bias and medium ABS lets you carry speed deep, rotate on entry with coast diff.
• Club (both instances) and Village/Loop exit: traction is everything — early, progressive throttle with 0.35 power diff prevents wheelspin, maximises exit speed onto the straights.
• Luffield: tight, low-speed — sacrifice entry speed for a clean, early throttle application to maximise the run to Woodcote and onto the start/finish straight.
